title: [The age-related characteristics of feather formation in birds and the physiological role of sulfur as sodium sulfate in keratin synthesis in the plumage].
abstract: There were studied formation's processes of feathering in chickens and goslings and role of sulphur sulphate in synthesis of keratin's feathers. It is established, that sulphur sulphate sodium is used for synthesis of precursors of keratin's feathers. The including of 35S-sulphate natrii regulates the intensity of feather's growth. The content of sulphur in amino acids containing sulphur in feathers of chickens for period from 1 till 60 days of age is increasing from 6.34 to 94.47 per cent. Fattening in composition of feed the sulphate natrii stimulates by chickens and goslings the intensity of feather's growth and metabolism of sulphur in skin.
